Developing Learning Model Base on PMR Approach at Senior High School to Improve Student's Motivation

There are several factors that cause the low achievement of students' mathematics learning outcomes in several senior high schools in the Dharmasraya district, the main factor is many students have difficulties in solve mathematic problems in their daily life, that caused the low of students achievement of students, including daily assessment and national assessment. The purpose of this research is for developing learning model base on realistic mathematic education (RME) approach. Developing learning model on topic Implementation of sequences and series based on RME is an effort for helping students in solving mathematics problems that they find in their daily life. The subject of this research is students grade XI of SMAN 1 Koto Salak. The method of this research used is design research using the Plomp development model. The techniques of data collection implemented using observation, questionnaires and assessment of mathematical test. The techniques of data analysis used are descriptive quanlitative and quantitative. The results of this research showed that the learning design with topic Implementation of sequences and series based on PMR approach has; The average value of HLT validity is 4.11 with a very valid category. The practical test of learning books applying PMR-based sequences and series by teachers and students is 85.02 and is classified as very practical. The average value of students' motivation in learning after being tested 83.3 and it means PMR approach also can improve student's motivation in mathematics learning.
